Wattleseed Acacia are perennial woody crops of varying age and size with some reaching 4m tall and 5m across. [4] Their large size and multiple stems is an impediment to harvesting and has resulted in the development of several strategies of collecting seed pods, including 'finger stripping' of pods off of foliage, 'butt shaking' of the tree to dislodge pods, and whole biomass harvesting.

Sandplain wattle grows as a tall shrub or small tree typically to a height of 2 to 5 m (6 ft 7 in to 16 ft 5 in) but can grow as tall as 8 m (26 ft). [4] It is able to form suckers and form dense colonies. It has glabrous branchlets that are often covered in a fine white powdery coating giving it frosted appearance. [3]
Wattle sign at Olive Pink Botanic Garden, Alice Springs, Australia (2005). The seed pods, flowers, and young leaves are generally edible either raw or cooked. [41] Aboriginal Australians have traditionally harvested the seeds of some species, to be ground into flour and eaten as a paste or baked into a cake.
The straight to slightly curved pale brown coloured seed pods that form after flowering have a length of up to 9 cm (3.5 in) and a width of 6 mm (0.24 in) and contain black, oblong to ovoid shaped seeds with a length of around 7 mm (0.28 in) and a width of 4 mm (0.16 in).
The tree's seeds number about 65 per gram. [7] A. maidenii can be propagated from seed but, in order to increase the germination rate, the seed should be treated first. It can be soaked in hot water or the seed can be nicked or otherwise mechanically scarified, so that water will penetrate the seed's hard coating and induce germination.
Acacia cultriformis, known as the knife-leaf wattle, dogtooth wattle, half-moon wattle or golden-glow wattle, is a perennial tree or shrub of the genus Acacia native to Australia. It is widely cultivated, and has been found to have naturalised in Asia , Africa , North America , New Zealand and South America . [ 1 ]
Following flowering brown seed pods form that have an oblong shape and are around 8 cm (3 in) in length and 12 millimetres (0.472 in) wide. The pods are flat but raised over each seed. [ 3 ] The hard shiny black-brown [ 4 ] seeds have an ovoid shape and are about 5 mm (0.197 in) with a width of around 3.5 mm (0.138 in).
Acacia symonii, also known commonly as Symon's wattle, [1] is a tree or shrub belonging to the genus Acacia and the subgenus Juliflorae that is endemic to parts of arid central Australia. Description [ edit ]
